Predictors of Pain Outcomes in Patients With Painful Temporomandibular Disorders.

Objectives: Baseline characteristics may predict treatment response in patients with painful temporomandibular disorders (TMD), e.g., higher baseline Characteristic Pain Index (CPI) scores associated with higher CPI following treatment. This study quantitatively estimated the association of baseline characteristics with pain at follow-up.
Methods: In this prospective cohort study, TMD pain patients (n=1901) sought treatment for their TMD pain in 182 dental practices enrolled in the National Dental Practice-Based Research Network (NationalDentalPBRN.org). CPI (0 -100 scale) was used to measure patient pain intensity at baseline, 1, 3, and 6 months. Proc MIXED was used to assess adjusted estimates of the independent effects of time and 15 predictors in a repeated measures analysis. Risk factors were identified by their higher CPI than the overall study means at each follow-up, and protective factors by their lower CPI means.
Results: Eight of the 15 baseline predictors were both risk factors for higher CPI at 6 months and protective factors for lower CPI.(Table 1)
Conclusions: Independent levels of 8 baseline characteristics serve as indicators of pain outcomes at 6 months following initial assessment by Network practitioners. They can be used to identify patients in need of specialized treatment.
